To all whom it may concern.-

Be it known that I, SAMUEL A. BENNER, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Car Parts; and I do hereby declare the following to be a full, clear, and exact description thereof. My invention relates to improvements in car parts and is particularly concerned with the provision of an improved blank or section from which the desired car part may be constructed. The object of the invention is to reduce the intrinsic weight of the frame or body member of a car part to a minimum, to lower the cost of production and at the same time to provide a structure of much greater strength than has been heretofore found practicable in order that the car part may be advantageously employed in the construction of heavy tonnage cars without materially increasing the Weight of the car itself. The blank or section. from which the car part is to be constructed according to this invention is equally well adapted for use as the body of a truck bolster, a body bolster, truck side frame, brake beam center or side sill or end sill of a car.

In the drawings which illustrate preferred forms of the invention, Figure 1 shows one form of section from which the car part may be constructed; Figs. 2 and 3 illustrate modified forms of sections respectively; Fig. 4 is a view inside elevation indicating the manner in which the blank or section may be cut or sawed to adapt it for use in the construction of the car parts; Fig. 5 is a view in side elevation of a truck side frame exemplifying one adaptation of the invention; Fig. 6 1s a longitudinal central section of the frame shown in Fig. 5; Fig. 7 is a transverse section on the line 77 Fig. 5; Fig. 8 is a view in side elevation indicati-ng an adaptation of the invention for a truck bolster; Figs. 9 to 18 inclusive indicate modified forms of the blank or body section adapted for use as the body portion, of the car part. Figs. 19 and 20 show further modifications.

. In the embodiment of the invention illustrated in Figs. 1 and 4 to 8, inclusive, and

referring first to Fig. 1, my improved form ofsection or blank comprises a rolled section having a comparatively thick transverse web 1 from one side of which projects a plurality of flanges such as 2 and 3, and from the opposite side corresponding flanges 4. and 5. The first step in 'the utilization of this blank after it is rolled is to saw or otherwise cut the web 1 intermediate of its ends as between the points A and B through from side to side and longitudinally of the web, as at 6 Fig. 4, thus dividing the web into base members 7 and 8. The base member 7 thus forms with the flanges 2 and 3 a continuous channel member and the base member 8 forms with the flanges 4 and 5 at the. opposite side of the web a second continuous channel member. These channel members unite at each end of the blank to form double channeled or reinforced ends for the car part.

In utilizing this blank so prepared 01 the construction of a truck side-frame, or example, the upper channel. member 27.? is bent or stretched upwardly as indicated in Fig. 5 and the lower channel member 4-8-5 is bent or stretched downwardly to form the tension member of a truck. side frame. The ends of the upper flan es 2 and 3 may be conveniently sheared ed as at 9, 9, and the lower flanges 4 and 5 sheared 0d at 10, 10, to form seats for the journal boxes 11 which may be secured to the opposite ends of the frame by the bolts 12. A suitable form of pedestal 13 may be interposed between the pressure and tension members of the frame, said pedestal having flanges 14 and 15 which may be riveted or bolted through and through to the channel member flanges 2 and 3, and 4 and 5, respectively.

Thus it will be seen that my improved rolled blank provides an unusually efficient body structure for a truss frame of any sort,

since the truss elements, such as the compression and tension members are in the form of continuous channels, each having a complete and solid base member extending continuously throughout its length. Furthermore, the base members or Webs of these channel shaped truss members are-united at the ends of the body, thus presenting their combined thickness and strength at their extremities, thus affording anunusually strong structure at the ends, so that when such blank is utilized as the body of a truck side frame the flanges may be cut away to any convenient extent as illustrated in 5 and 6 to afiord proper seats for journal. boxes, or when the blank is used for a truss tending entirely throughout their width as well as continuously throughout their length .so that said members are adapted to resist not only the bending and stretching strains to which they are ordinarily subjected but also to resist lateral and twistingstrains also commonly sustained in the use of a car art. Again, by leaving the thickness of the web at'the opposite ends of the structure and beyond the transversely cut portion intact, these ends possess unusual strength. Furthermore, the channel portions forming the tension members are in all cases immediately below the compression member instead of being offset to one side or intermediate the sides as in the case where the web is sheared at right angles to its flat faces. 1

As indicated in Fig. 1 the transverse web 1 maybe so out that the base 7 of the upper or compression channel member is of greater thickness than the base member 8 of the lower or tension channel member, thus mak ing a heavier compression member to bear the greater strains to which such member is ordinarily subjected. Also the flanges 4 and 5 maybe of less thickness than the flanges 2 and 3 and may correspond in thickness to the base 8 of the lower channel. Similarly, the base 7 of the. upper channel may correspond in thickness to the greater thickness of the flanges 2 and 3. The exact dimensions of the several parts will of course be determined by practical experience, but in general it may be said that the total outside width of the section may be eight inches, the flanges 2 and 3 and the base 7 of the upper channel may each be one inch in thickness while the flanges 4: and 5 and the base 8 of the lower-channel member may be substantially three quarters of an inch in thickness. It is, to be understood, however. that these dimensions are given by way of suggestion only.

In constructing a car bolster from a section of this diameter, as shown in Fig. 3, the blank may be sheared along the line (i as before and between the points a and 7). The ends of the blank may then be clamped in a suitable pressand the lower channel or tension member of the bolster comprising.

the flanges l 55 and the base 1 may then a be bent or or both bent and stretched downwardly from the upper channel member comprising the upper flanges 3, 4' and the channel base 7'. The compression and tension members may then be secured together and reinforced by means of rolled, pressed or cast strut members such as I-beams 15. This form of bolster has the particular advantage that the channel bases 7 8 may be bored at 16 and 17 respectively to receive the king-bolt, thus affording ample lateral support for said bolt,

Of the modified forms of the section from which the desired structure may be produced, that in Fig. 2 comprises the thick web 18, the edge flanges 19 and 20 and the opposite flanges 21 and 22 which are preferably inset from the side edges of the blank, and if desired the inner faces such as 23 of the upper flanges may be parallel and in the same plane as the outer faces, as 24, of the lower flanges. In this case the web may be sheared longitudinally and intermediate of its ends along a line within the thickness of the web indicated at 25.

In Fig. 3 the section resembles that shown in Fig. 1, exceptthat the flanges 26, 27 may be of the same thickness as the flanges 28 and 29, and a thickened web may be cut or sawed along the line 30.

In Fig. 9 the blank comprises a transverse web 31 having laterally projecting portions 32 and 32, extending beyond the flanges 33, 33 on one side of the web and the flanges 34, 34 out-he opposite side. The extensions 32 of the web aflord a breadth of.base for the pedestal of a side frame or for any other purpose where such-broad base is required to reinforce the structure against lateral thrust.

In the form shown in Fig. 10 the blank may comprise the thickened web 35 and the series of flanges, here four in number, 36, 36, 36, 36, whereas the flanges 37, 37, on the opposite side may be two in number and may be positioned in alinement with the intermediate flanges 36 on the upper side, respectively. The web may be sheared along the line 38, thus affording a broad web 39 for the base of the tension member equal in width to the broad web 40 of the compression member.

In Fig. 11 the blank comprises a thickened web l1 and a plurality of flanges 42 and a corresponding number of flanges 43 projecting from the opposite side of the web and as here shown, in alinement respectively with the flanges 42. The transverse webmay be sheared along the line 441 to form the bases. respectively, of the upper and lower "channel members.

Fig. resembles the structure of Fig. 9 except that the flanges 4.3 on one side may be greater in thickness than the flanges -15 on the opposite side of the web 1? and the web may be'cut along the line 48 forminga base 49 for the tension member of substantially the same thickness as the flanges 46 and abase 50 for the compression member of substantially the same thickness as the flan es 45 thereof.

T e form shown in Fig. 13 comprises a combination of that shown in Figs. 2 and 9, respectively, in that the web 51 has not only the flanges 52 at one side and the flanges 53 at the other, but also the lateral extensions 54. Likewise the web has the greater thick ness between the flanges 53 so that when sheared along the line 55 the upper channel is provided with a base 56 prolonged into the extension 56 and the lower channel is provided with the base 57.

In Fig. 14 the blank comprises a combination of the forms shown in Figs. 2 and 10, in which the web 58 has a series of flanges 59 on one side and. a pair of flanges 60 oil the opposite side, the webbeing thickened at 61 to supply the base for the lower channel member when the web is sawed along the line 62.

In Fig. 15 is illustrated a form of blank peculiarly adapted for use in a truck bolster in which the thickened web 63 is provided with the upstanding flanges 64 of somewhat more than usual width, which in the construction of the bolster may, if desired, be bent inwardly or outwardly at 65 to form the compression member in the form of a partially closed member or a laterally strengthened member, and thus also afl'ording a base or rest for the body or other corresponding bolster. This blank is also provided with the opposite flanges 66 and the thickened portion of the web 67 forming the lgase of the lower channel or tension mem- In Fig. 16 the blank comprises the web 68 having a plurality of flanges 69 on one side arranged in pairs, and opposite each pair of said flanges are the flanges 70. The web is thickened at 71 and 72 to be shearedalong the line 73 to form the complete lower channel members opposite the channel members formed by the pairs of flanges 69, respectively, while the central portion 73 of the webforms a complete transverse base for the upper or compression member.

In F ig. 17 the blank consists of the web 74, the flange 75 on one side and the flange 76 on the opposite side; This web may be severed along the line 77 forming truss members having transverse bases and these upstanding reinforcing flanges.

In Fig. 18 the blank comprises the base 78, the pair of flanges 79 and the flange from the opposite side 80. This blank may be severed along the line 81 to forin a truss construction having one truss member in the shape of a channel member and the other having a transverse base and a flange 80.

.truss members.

In Fig. 19 the blank comprises the web 82 havinga flange 83 on one side and a reinforcing member 84 on the opposite side. The web is severel along line 85.

In Fig; 20 the blank comprises the web.

86 and the reinforcingmember or flange 87 on one side andthe reinforcing member 88 on the opposite side. This web likewise is severed along the line 89. v

The form shown in Figs. 18, 19 and 20, inclusive, are particularly well adapted for use in brake beam constructions in which when the web is severed, the portion of the blank on one side of the cut may remain straight, while the one on the opposite side may be bent or stretched to form a truss member, reinforcing the straight member.

While in most instances the word flange has been used to designate the reinforcing ridges or ribs, on opposite sides of the web, it is to be understood that this term is not necessarily limited strictly to straight flanges, such as shown in the majority of figures, but may also apply to reinforcing ribs ormembers of varied shapes such for example as illustrated at 84 and 88 in Figs.

4 19 and 20.

While I have herein shown and described several modifications of the invention it is to be understood that-the same may be modified in structure and relative arrangement of parts within the scope of the appended web being cut or sawed intermediate "its ends in a plane substantially parallel with its opposite flat faces, whereby the parts on the opposite sides of said out may be bent gr stretched to form continuous truss memers.
